Analysis of Touch Voltage in TN-S Earthing System

2018 IEEE International Conference on Environment and Electrical Engineering and 2018 IEEE Industrial and Commercial Power Systems Europe (EEEIC / I&CPS Europe), 2018
This paper presents touch voltage analysis in TN-S connected earth system. For this purpose, calculation of touch voltages and touch durations (as per IEEE and International Electrotechnical Committee (IEC) standards) with equivalent formulas is done for different sizes of cable and protective conductor (PE). Cable ampacity calculations for underground

Field Measurements Of Touch And Step Voltages

IEEE Transactions on Power Apparatus and Systems, 1984
This paper presents the study of a measurement technique for touch and step voltages and the results of measurements obtained inside and outside substations. Details of a low-voltage and a highvoltage method of current injection are given. Setups for measuring the shock touch voltage and shock step voltage are characterized, in which the effect of foot

Simplified conservative measurements of touch and step voltages

1999 IEEE Industrial and Commercial Power Systems Technical Conference (Cat. No.99CH36371), 2003
Protection against electric shock requires grounding systems that must be designed primarily to keep touch voltage (E/sub t/) and step voltage (E/sub s/) to a safe value. Testing of the efficiency of a grounding system is mandatory to verify the capability to satisfy the protection requirements at the end of the construction and periodically in the ...

Analysis of transfer touch voltages in low-voltage electrical installations

Building Services Engineering Research and Technology, 2010
Protection against electric shock in our homes and work places is one of the most important priorities for electrical services engineers who are now designing electrical installations to conform to the requirements of the 17th edition IEE Wiring Regulations (BS7671: 2008).

An alternative approach for touch and step voltages measurement in high-voltage substations

Electric Power Systems Research, 2016
Abstract This paper presents the study of a measurement technique for touch and step voltages. In essence, we elaborate an approach which is very similar to the measurement of the grounding system impedance. In addition, the main focus is on the measurements at energized substation where different types of coupling between the test leads, grounding ...

Electrical safety and touch voltage design

Building Services Engineering Research and Technology, 2010
The provision of safe and reliable means to afford protection against electric shock in the built environment is deemed one of the most important design elements for electrical services engineers who design low voltage electrical installations to conform to BS7671: 2008 (17th edition IEE Wiring Regulations) and ET 101:2008.

A Practical Probabilistic Method to Evaluate Tolerable Step and Touch Voltages

IEEE Power Engineering Review, 1984
A simplified probabilistic method to calculate the risk of the human body withstand voltage to be exceeded by step and/or touch voltages appearing during abnormal system fault conditions is presented in this paper. The determination of density probability functions and cumulative distributions are done by using characteristic parameters of well known ...

Experimental measuring of the touch voltages in large compensated networks

2012 Electric Power Quality and Supply Reliability, 2012
A connection between a phase conductor and the ground in MV networks is called earth fault. The fault current in this case does not depend on the point of the fault, but only on the total capacity (size) of a network. Distribution system operator (DSO) sometimes needs to operate the large network which means operating of the network with big capacitive
